2. Gouy balance - Wikipedia

   en.wikipedia.org/wiki/Gouy_balance

   Schematic diagram of Gouy balance. The Gouy balance, invented by the French physicist Louis Georges Gouy, is a device for measuring the magnetic susceptibility of a sample. . The Gouy balance operates on magnetic torque, by placing the sample on a horizontal arm or beam suspended by a thin fiber, and placing either a permanent magnet or electromagnet on the other end of the arm, there is a ...

3. Faraday balance - Wikipedia

   en.wikipedia.org/wiki/Faraday_balance

   A Faraday balance is a device used to measure magnetic susceptibility, a property of matter is related to the force experienced by a substance in a magnetic field. Various practical devices are available for the measurement of susceptibility, with differences in the shape of the field and the way the force is measured. [1] In the Faraday ...

4. Faraday effect - Wikipedia

   en.wikipedia.org/wiki/Faraday_effect

   Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...

5. Magneto-optic Kerr effect - Wikipedia

   en.wikipedia.org/wiki/Magneto-optic_Kerr_effect

   The magneto-optic Kerr effect manifests when light is reflected from a magnetized surface and may change both polarization and reflected intensity. The magneto-optic Kerr effect is similar to the Faraday effect, which describes changes to light transmission through a magnetic material. In contrast, the magneto-optic Kerr effect describes ...

6. Geometrical frustration - Wikipedia

   en.wikipedia.org/wiki/Geometrical_frustration

   The frustration of a spin glass is understood within the framework of the RKKY model, in which the interaction property, either ferromagnetic or anti-ferromagnetic, is dependent on the distance of the two magnetic ions. Due to the lattice disorder in the spin glass, one spin of interest and its nearest neighbors could be at different distances ...

   You should also measure your current frames to make sure the new ones are a similar size. Pair offers only about 10 frame styles each for men and women, with five available for kids. But you can ...

8. Force between magnets - Wikipedia

   en.wikipedia.org/wiki/Force_between_magnets

   More precisely, the term magnetic moment normally refers to a system's magnetic dipole moment, which produces the first term in the multipole expansion [note 1] of a general magnetic field. Both the torque and force exerted on a magnet by an external magnetic field are proportional to that magnet's magnetic moment.

9. Visual weight - Wikipedia

   en.wikipedia.org/wiki/Visual_weight

   The visual weight and the balance of a figure inserted in an image can be determined using the lightness of the figure, the lightness of the ground and their sizes and positions interactions in the composition visual. We establish that an image is totally balanced when the resultant force is located in the geometric center of the image.
